If you put a market order at 22:00 on the das, will IG charge you 2 points spread or 5? 17:30-22:00 it is 2 points after 22:00 5 points. But what is AT 22:00. I assume 5 points?
I believe it is 5 point spread. If order is opened at 220000 it is opened at >= 220000. Sometimes the order is executed a second late or so, which for sure means 5 point spread.
